摘要: A method for determining the concentration of carbonate salts in solutions containing other inorganic salts. The method includes converting the carbonate salts to carbon dioxide by acidifying the sample, sweeping the acidified solution with an inert gas to strip the carbon dioxide from the solution and contacting an ion-selective gas-sensing electrode with the gas stream. The electrode includes a buffered solution which changes in pH depending on the concentration of carbon dioxide in the gas stream thereby providing a measure of the carbonate salt concentration in the sample.

摘要: An oxidized halogenated polymer is prepared by a process comprising (a) forming an admixture of an acidic oxidizing agent and a suspension of a particulate halogenated polymer in a polar liquid; (b) heating the admixture to a temperature sufficient to initiate the reaction between the polymer and the oxidizing agent; and (c) continuing the reaction until an oxidized polymer having a preselected extent of oxidation is obtained. At least one addition polymerizable compound is, optionally, grafted to the oxidized halogenated polymer. The oxidized halogenated polymer and graft copolymers thereof have physical properties different from the halogenated polymer and graft copolymers thereof. Certain graft copolymers are non-caking or free flowing.
